IMPROVEMENT EN WATER-METERS.

Specification forming part of Letters Patent No. 14,694, dated May 9, 1871 application iled April 2o, 1871.

To all whom it may concer/n:

Be it known that I, J oHN P. LINDSAY, of the city, county, and State of New York, have invented certain Improvements in Tater-Meters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making a part of this specification, in which- Figure l represents a front elevation of the meter, portion of the front head being broken away to show the interior arrangement of the parts. Fig.v2 is an axial section, showing the valvel partly in elevation. Fig'. 3 is a rear ele-r vation, the rear head and the valve being removed to show the water-channels in the diaphra gm of the case. Fig. 4 is an elevation of the front head of the case, showing the inner side. Figs. 5 to l0 are illustrations in detail of the valve and-trigger, to be hereinafter referred to. Fig. ll represents a modification in the construction of the valve. Fig. l2 is an elevation, partly in section, showing a mod iication inthe construction ofthe meter. Fig. 13 is an axial section of the meter, shown in elevation in Fig. l2.

The same letters of reference are used in the different gures in the designation of identical parts.

This invention, relating to water-meters, consists in various novel features of construction, combination, and arrangement of parts, which will be generally described in the following description, and specifically pointed out in the claims.

The operative parts of the meter are inclosed in a short cylindrical case, A, closed by heads at each end, the front one of which is marked A1, and the rear one A2. A solid diaphragm, B, is formed in the rear end of the case, coming in contact with the rear head A2, as indicated in Fig. 2. In the space between this diaphragm and the front head A1 an oscillating disk, C, is arranged, which is constructed with a circumferential flange, O1, of such width as to snugly it between the diaphragm and head of the case. The diameter of this disk is considerably less than that of the bore of the case, so as to form an annular chamber, D, between the two. This chamber is divided by a partition, A3, secured to the rim of the case, and an enlargement or wing, O2, on the oscillating disk. In the diaphragm B are formed channels B1 and B2, one upon each side, which encircle the valve passing through the center, and pass thence outward, and communicate with the water chamber D, upon opposite sides of the partition A3, a port, b, being bored through the diaphragm to connect the channel B2 upon its rear side with the said chamber upon the opposite side. The iow of the iuid passing through the meter is controlled by a valve, which passes through the center of the case and oscillating disk, forming the axis upon which the latter turns. rIhe valve is composed of acylindrical hollow case, E, iitted with a tubular plug, F, which communicates at one end with the eductionpipe G, and `at the other end with the eduction-'pipe Vnot shown. The tubular plug is constructed with a solid diagonal partition, F', and the end connecting with the pipe G has two induction-ports, f and j, cut through the shell, whilek upon the other `side of the partition are formed the eductionports gand g. Iheinduction and eduction ports are formed upon opposite sides ofthe plug. Oorresponding induction-ports e and el and eduction-ports d and d are cut through the case E, which upon the outside communicate with the annular portion of the channels B1 and B2, respectively. The arrangementof these ports in the plug and its case with reference to one another is such that when the induction-ports fe coincide so as to admit the iiuid into the channel B2, as shown in Fig. 2, the induction-ports l time the induction-ports d and g coincide to discharge the fluid from the channel B1, while communication between the eduction-ports d and g is shut oi'. In reversing the valve the ports assume the position shown in Fig. 6, and water now iiows into the channel B1, and is discharged from the channel B2. rlhat portion of the case E of the valve which protrudes through the oscillating disk O is constructed with a weighted wing or arm, E1, by means of which the case is oscillated on the Ahollow plug, held stationary, for the time being, at the end of each stroke of the oscillating' disk to change the position of the ports, and, consequently, reverse the iiow of and el do not communicate 5 at the sameA the water through the meter. The extent of movement of the valve-case on the plug is controlled by studs c and 01 on the disk. rEhe valve E F turns during the greater portion of the stroke with the oscillating disk, to which it is, during that time, locked by means of a trigger, H, the enlargedV endh of which enters the recess c2 in the rim of the disk, and one or the other of corresponding recesses c2 and e3 in the weighted arm El of the valve-ease, while its reduced end h1 projects into a notch,

f2, cut in a collar of the plug F. The trigger is constructed with aprojecting stud, h2, which plays in a groove, H', formed in the interior side of the head A1. This groove is of the proper length to permit of the required oscillations of the disk C, and is for the greater portion concentric with the axis of the latter 5 but near each end it is turned outward, as best seen in Fig. 4, in order to slide the trigger outward until both the plug and its case are unlocked from the disk. The meter being always arranged in the position substantially as shown in Fig. l, the moment the valve-case is thus released from the oscillating disk its weighted arm E1 will cause it to turn on the plug to the extent permitted by one or the other of the studs c or c1, by which the farther movement of the arm is stopped. The valve having thus been reversed, the oscillating disk begins to move in the opposite direction, and the plug and valve-case are again locked to it, and travel with it to the end of the return stroke. A projection, a, on the head A1, extends into a groove, f3, in the plug F, as shown in Figs. 2, 7, and 8. The ends of this groove do not meet, it being only made of just sufficient length to permit the plug to travel with its inclosingcase up to the moment when it is released from the disk C. At that moment the projection c comes in contact with the metal between the ends of the groove f3, and holds the plug stationary 'while the case turns on it.

In the modification shown in Figs. 12 and 13 the diaphragm in the case is dispensed with, and the channels B1 and B2 are formed in the oscillating disk, which is shown as constructed in the form of ra wheel with spokes, two of which are made hollow to constitute the water-passages. In this case the ports of the valve-case open into an annular groove formed either in the case itself, as shown, or in the hub of the wheel, so that the ports will always communicate with the channel Bl and B2. These now open into the water-chamber D on opposite sides of the wing G2 of the oscillating disk C.

The valve shown in Fig. 11 differs from that heretofore described, in having an annular chamber, E2, formed in the metal of the case, into which chamber the water is discharged instead of into the other end of the plug. In the position of the parts shown in Fig. 2, the water iows from the induction-pipe G, through the ports e and f of the valve and channel B2, into the water-chamber D, driving the oscillating disk in the direction of the arrows in Fig. I, so as to force the water upon the other side of the wing G2, through the channelB1 and ports d and g of the valve, into the exhaust end of the plug F. On arriving at the end of the stroke in this direction, the valve is reversed in the manner set forth, and the water then lows, through the ports f1 and el and channel B1, into the opposite end of the water-chamber D, driving the oscillating disk in the opposite direction to that indicated in Fig. I, and causing it to force out the water before its wing U2, through the channel B2 and ports d and g. The waterchamber D must be made to hold a definite quantity of water, by weight or measure; and a suitable registering apparatus is to be connected with one of the moving parts of the meter to indicate the number of oscillations of the same, and the quantity of water passed through meter.

What I claim as my invention, and desire to secure by Letters Patent, is

I. A water-meter containing a circumferential measuring-chamber, D, formed between the case and an oscillating disk, U, into which chamber the water flows alternately on one side or the other of a partition, A3, to be discharged by the wing C2 of the oscillating disk at the opposite side of such partition, substantially as set forth.

2. A water-meter containing the circumferential divided water-chamber A A3, in which an oscillating wing, G1, operates, and a valve arranged centrally within the chamber D to induct the water from the center to the circumference, and discharge it from the circumference through the center of the meter, substantially in the manner set forth.

3. The valve, composed of the hollow case E and tubular plug F divided by a partition, F1, and containing two sets of induction-ports, ef and e1 f1, and two sets of eduction-ports, d y and d g', to operate substantially as set forth.

4. The combination of the oscillating disk C, valve-case E, and tubular-divided plug F F', arranged relatively to one another, as set forth, so that they will move conjointly during the greater portion of each stroke of the disk, and be released from one another near the end of each stroke, to permit the valve-case to turn on the plug held stationary for the time being to reverse the position of the stroke.

5. In combination with the notches e2 and e3 in the arm E1 of the valve-case E, and notch]02 in the plug F, the trigger H and camgroove H in the head Al of the case, all arranged to operate substantially as set forth.

6. The combination of the oscillating disk C, wing C2 thereon, and partition Al in the water-chamber D, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
